Abstract: Provided is a method for manufacturing a glass fiber strand in which a glass fiber strand is formed by bundling a plurality of glass fiber filaments comprising molten glass drawn out from a nozzle, wherein said method for manufacturing a glass fiber strand is capable of detecting breakage of the glass fiber filaments in a more reliable manner. This method comprises: an image capturing step for generating a plurality of items of image data by continuously capturing images of a plurality of glass fiber filaments f; an image processing step for extracting, from the image data, a high luminance object having a luminance of a prescribed value or more; and a breakage detection step for detecting that a glass fiber filament f has broken on the basis of the results of the image processing in the image processing step.

This method comprises: an image capturing step (STEP-1) for generating a plurality of items of image data by continuously capturing images of a plurality of glass fiber filaments f; an image processing step (STEP-2) for extracting, from the image data, a high luminance object 100 having a luminance of a prescribed value or more; and a breakage detection step (STEP-3) for detecting that a glass fiber filament f has broken on the basis of the results of the image processing in the image processing step.

Abstract: A memory remote control device which comprises a wave shaping circuit for shaping a received remote-controlled signal and for outputting a pulse signal and an envelope signal, and a microcomputer operable to convert the remote-controlled signal into data for storage in a memory and for reproducing the remote-controlled signal on the basis of the data stored in the memory.
